Global Positioning System
GPS stands for global positioning system. It uses a network of satellites in orbit. Although the GPS is used as a navigation device, it is also a form of communication to the vessel.
Sailboat Battery Charging
Like a water bucket, batteries have a specific storage capacity and must be refilled/recharged when their contents of energy are depleted.
Sailboat Wind Power Generators
Wind-power generators are typically installed only on ocean-crossing vessels, where the vessel is away from the marina for extended periods of time and where there is a need for conserving onboard fuel.
Alternating Current and Direct Current
In your house, your wall outlets deliver alternating current (AC) electricity. The electricity provided to your house and your marina from the national electric grid is AC. Most of the devices...
Tacking and Gybing Maneuvers
Tacking when you want to sail in a direction to exactly where the wind is coming from— guess what—you can’t! The best we can do is to follow a zig-zag course by sailing at about 30 to 40 degrees off the wind...
Dock Slips Docking Techniques
Wind coming into the dock slip channel and your boat is to be docked stern-to, steer into the slip channel...
Propwalk factors – The p factor
There are two combined reasons that work in unison to create propwalk.
Boat Safety Sound Signals
Sound signals are defined and prescribed in the Navigation Rules for International and Inland Waters. Sound has an advantage over light signals, in that it can be used when vision fails.
Personal Flotation Devices
The terms “life jacket” and “PFD” are interchangeable, with the latter used in the USA and the former used in most of the rest of the world.
Understanding Energy and Power
Energy: The concept of energy is likened to water for the easiest understanding. A bucket of water holds a specific amount of water which is measured in a quantity of gallons or liters. It is finite; when it is all drained out, it is gone. To gain more, it must be replaced from a source.
Key Sailboat Instruments

Take Note When the Boat Heels Over or Stands Up
At a sailing group meeting, someone mentioned they were having trouble determining if the boat was pinching or not.
Electronic Navigation
We are well into the 21st century. Chances are that within 30 feet (10 meters) of you right now there are 2-3 GPS-enabled potentially lifesaving devices...
Vessel Lights and Shapes
Nighttime can be a beautiful time to sail. However, night vision is not the same as day vision and so rules have been established to ensure safety.
Ferrying Docking Technique
Ferrying is a docking technique whereby you can maneuver your boat in high wind and current easily.
The Deck – Getting Familiar with a Charter Boat
Gaining knowledge about the boat, its systems, and its equipment is a great starting point for any sailing adventure.
Propwalk – The Wash Lift effect
The wash-lift effect has been documented heavily by Dave Geer who is one of the worlds leading propeller engineers.
Navigation Tools
No matter the chart in use, the navigator’s work largely involves the determination of direction and distances. The most useful tools for actual chart work are...
Understanding How Airflow Creates Lift
Understanding how Airflow creates lift and the need for smooth airflow when sailing...
Sailboats Under Power
A Sailboat Under Engine Power is a Power-Driven Vessel Rule 3(c) The term “sailing vessel” means any vessel under sail provided that propelling machinery...
Sailing Personnel Emergencies
As the skipper of a vessel, you are expected to be able to handle situations thrust upon you at a moment’s notice. Many of these situations are boat-related issues, but there are also crew injury issues for which you should be prepared to assess and handle at least enough until professional assistance arrives.
